dbus.lowlevel module
Low-level interface to D-Bus.
- class dbus.lowlevel.ErrorMessage(reply_to: Message, error_name: str, error_message: str or None)
Bases:
dbus.lowlevel.Message
An error message.
- append(*args, **kwargs)
Set the message’s arguments from the positional parameter, according to the signature given by the
signature
keyword parameter.The following type conversions are supported:
D-Bus (in signature)
Python
boolean (b)
any object (via bool())
byte (y)
string of length 1 any integer
any integer type
any integer
double (d)
any float
object path
anything with a __dbus_object_path__ attribute
string, signature, object path
str (must be UTF-8) or unicode
dict (a{…})
any mapping
array (a…)
any iterable over appropriate objects
struct ((…))
any iterable over appropriate objects
variant
any object above (guess type as below)
Here ‘any integer’ means anything on which int() or long() (as appropriate) will work, except for basestring subclasses. ‘Any float’ means anything on which float() will work, except for basestring subclasses.
If there is no signature, guess from the arguments using the static method Message.guess_signature.
- copy() -> Message (or subclass)
Deep-copy the message, resetting the serial number to zero.
- get_allow_interactive_authorization(bool) None
Get allow interactive authorization flag.
- get_args_list(**kwargs) list
Return the message’s arguments. Keyword arguments control the translation of D-Bus types to Python:
- Keywords
- byte_arraysbool
If true, convert arrays of byte (signature ‘ay’) into dbus.ByteArray, a str subclass. In practice, this is usually what you want, but it’s off by default for consistency.
If false (default), convert them into a dbus.Array of Bytes.
Most of the type mappings should be fairly obvious:
D-Bus
Python
byte (y)
dbus.Byte (int subclass)
bool (b)
dbus.Boolean (int subclass)
Signature (g)
dbus.Signature (str subclass)
intNN, uintNN

double (d)
dbus.Double

Object path (o)
dbus.ObjectPath (str subclass)
dict (a{…})
dbus.Dictionary
array (a…)
dbus.Array (list subclass) containing appropriate types
byte array (ay)
dbus.ByteArray (str subclass) if byte_arrays set; or list of Byte
struct ((…))
dbus.Struct (tuple subclass) of appropriate types
variant (v)
contained type, but with variant_level > 0

- get_sender() str or None
Return the message’s sender unique name, or None if none.
- get_serial() long
Returns the serial of a message or 0 if none has been specified.

- get_signature() Signature or None
- get_type() int
Returns the type of the message.
- static guess_signature(*args) Signature [static method]
Guess a D-Bus signature which should be used to encode the given Python objects.
